Early spatial changes in the posterior corneal surface after laser in situ keratomileusis.

Purpose: To evaluate the forward shift of the posterior corneal surface after myopic laser in situ keratomileusis (LASIK) relative to the residual stromal bed thickness and the ablation percentage of the total corneal thickness.

Setting: Department of Ophthalmology, Ilsan Paik Hospital, Inje University, Ilsan, Korea.

Methods: Three hundred sixty-three eyes of 182 consecutive patients who had LASIK were examined retrospectively.

Accuracy and predictability of the compensatory function of Orbscan II in intraocular pressure measurements after laser in situ keratomileusis.

Purpose: To evaluate the usefulness of the compensatory function of Orbscan II (Orbtek, Bausch & Lomb) for measuring postoperative intraoperative pressure (IOP) in laser in situ keratomileusis (LASIK) patients.

Setting: Department of Ophthalmology, Ilsan Paik Hospital, Inje University, Ilsan, Korea.

Methods: Two hundred ten patients had LASIK using the Hansatome microkeratome (Bausch & Lomb) and the MEL 70 G-scan laser (Aesclepion-Meditec) and were examined retrospectively.
